Definitions
- the invention relates to new, isotope-coded affinity markers for the mass spectrometric analysis of proteins as well as their production and use.
- Proteomics technology opens up the possibility of identifying new biological targets and markers by analyzing biological systems at the protein level. It is known that only a certain part of all possible proteins of the proteins encoded in the genome is expressed, whereby, for example, tissue type, development status, activation of receptors or cellular interactions influence the expression patterns and rates. In order to determine differences in the expression of proteins in healthy or diseased tissue, various comparative methods for analyzing protein expression patterns can be used ((a) S.P. Gygi et al., Proc. ⁇ atl.
- Isotope coding is implemented.
- the protein mixtures are then combined, if necessary fractionated or proteolytically treated and purified by affinity chromatography. After the bound fragments have been eluted, the eluates are analyzed by combining liquid chromatography and mass spectrometry (LC-MS). Couples or groups of with themselves only in the
- Isotope coding distinguishing affinity markers are labeled peptides are chemically identical and are eluted almost simultaneously in HPLC, but they differ in the mass spectrometer by the respective molecular weight differences due to different isotope patterns of the affinity markers. Relative protein concentrations can be obtained directly by measuring the peak areas. Suitable affinity markers are conjugates from
- Affinity ligands that are covalently linked to protein-reactive groups via bridge members. Different isotopes are built into the bridge members. The method was described using affinity markers in which hydrogen atoms were replaced by deuterium atoms ( 1 H / 2 D isotope coding sequence).
- the object of the present invention was to provide improved affinity markers.
- the invention relates to organic compounds suitable as affinity marker reagents for the mass spectrometric analysis of proteins of the formula (I),
- PRG stands for a protein-reactive group and L stands for an A and PRG covalently linking linker, wherein the linker L is an acid-cleavable group S of the formula
- Y for an optionally branched spacer group with a chain length of 1 to 10, preferably 1 to 5 non-hydrogen atoms and
- SK stands for the side chain of an amino acid
- the invention furthermore relates to the use of one or more differently isotope-labeled compounds according to the invention as a reagent for the mass spectrometric analysis of proteins, in particular for the identification of one or more proteins or protein functions in one or more protein-containing samples and for determining the relative expression levels of one or more proteins in one or more protein-containing samples.
- the acid-cleavable group S ensures a cleavage of the affinity marker as a predetermined breaking point under the action of acid.
- the predetermined breaking point enables the peptide fragments to be decomplexed by a much more efficient streptavidin-based affinity chromatography for biotin-modified peptide fragments. It is also advantageous that the tags remaining on the peptide fragments after acid cleavage have a significantly lower molecular weight and have a higher isotope density. Furthermore, the handling of the affinity markers is improved compared to the prior art by better solubility and by a crystalline or amorphous appearance.

- Affinity level A is used for the selective enrichment of samples with the aid of affinity chromatography.
- the affinity columns are provided with the corresponding complementary partners to the affinity ligands, which enter into covalent or non-covalent bonds with the affinity ligands.
